Pretty daring task of jumping on a 25MPH truck!
But this story reminds me of many stories reported by inexperienced journalist. You often see a track-hoe, or a back-hoe, or a crane and it's reported to be a "bull dozer"
This report says, "The man's blood sugar had dropped to a severely low level. He didn't know that he was diabetic until the episode."
If he was a diabetic, known or not, his blood sugar would have been high, probably extremely high!
By their report, what this fellow has is hyperglycemia, which means his body produces too much insulin.
Diabetes is hypoglycemia which is to little insulin. The only way a diabetic can have too low blood sugar is by injecting insulin or similar drug.
Apparently the reporter does not know the difference between hypoglycemia and hyperglycemia. Hypo (as in hypodermic needle, goes under the skin) is under, hyper is (as in hyper active) over.
Because it's printed does not mean it's fact. Including what I just typed!!!
